本文介绍了一个BroadcastReceiver实现中出现的问题及解决办法。当BroadcastReceiver的onReceive方法内包含UnsupportedOperationException时，会导致应用无法正常接收广播。文章提供了具体的代码示例，并说明了如何通过移除异常抛出来解决问题。

Unable to start receiver activitytest.example.com.receive.MyBroadcastReceiver: java.lang.UnsupportedOperationException: 接收不到

public class MyBroadcastReceiver extends BroadcastReceiver {
    public MyBroadcastReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        Toast.makeText(context, "received in MyBroadcastReceiver", Toast.LENGTH_SHORT).show();
//        throw new UnsupportedOperationException("接收不到");
    }
}

要去掉throw new UnsupportedOperationException 才不会报错
